   NorthGrid — css/resources.css
   AUDIT 2026-10-28 BW: New file. Styles for the Resources library
   (resources/index.php, resources/doc.php, resources/download.php error pages)
   and Find a NorthGrid Contractor (find-a-contractor/index.php). Loaded after
   css/ng-brand.css and uses its tokens. Every rule is scoped to an .ngr- class,
   so nothing here changes a shared rule on any other page.

   The lead forms here use .ngr-form, NOT .contact-form: js/main.js binds the
   first .contact-form on a page, rewrites its button to "Send Message" and posts
   a fixed homepage field list. These forms are posted by js/ng-lead-forms.js.
   .ngr-form copies the .contact-form card look from ng-brand.css.

   Contrast (pairs documented in ng-brand.css): Onyx on white 16.3, ink-2 on
   white 6.9, Chalk on Pine 9.8, Copper on white 5.9. Amber is only a fill or
   border here, never text on a light surface.
